[development] Critical bug in CCK - help from field module developpers needed

A critical bug has been discovered in CCK field data storage, which can result in possible data loss under some (rare) circumstances. Only a very limited number of field types are potentially affected, we need the help of contrib CCK fields developpers to help us list exactly which ones, so that we can extensively test the patch before committing it. See http://drupal.org/node/168204 for more info. Thanks all :-) (also posted on g.d.o - sorry for the spam)
